RESILIENfIjTIRE.

Tocllwhom itma'z mm.-

Be it known that'vve, JO Nv HSZWINGLER I and PHILLIP"C-.- ZWINGLER, citizens of the 7 United States,* residing at Mineral Ridge, in the -countyx'of Trumbull and Stat'ef'of Ohio, have invented certain new and useful Improvements in Resilient Tires, of which supports. a c

It yvilljthus beapparent'that each individual plate will be tied or secu'red to an adjoining ne sothat there is nomovement circumferentially at the tread portion of theshell'.

In order to. further-secure theseplates" to j i se e ndpes v y, v n y re at ve. movement or; telescopic tendency therebe tWeen,j-they ma also" be fastened-at their" ends means'of the rivets 10. These 5 faSjtniligs not only unite the "adjoining plates, but maintain theffolded ends of the plates in bead form, as will be-apparent from Fig. 1. With fthefarrangement 'de' scribed, whereby allfof the-plates are; fas- I tened together, it will bei'apparent that the shell Will 11ml yield circumferentiallmibut samejpreferably includes a plurality ofinx 1 will give the desired resilience entirely by lateral expansion of the united plates.

As will be clear from the foregoing description, and inspection of Fig. 1, the beads 8 formed at the edges 6 of the internal shell are interlocked within the opposite grooves 4 of the rigid demountable attaching rim 2. Thus, the opposite edges of the arched shell are not only connected and held in spaced relation to maintain the proper width at the base of the tire, but a complete metallic tube is formed by the rim 2 which also provides the demountable element. For the purpose of completing the tire body, the spring shell or support 1 is preferably enveloped by a conventional rubber and canvas, or equivalent, covering 11, which constitutes the external shoe of the body. This external covering shoe is provided with a thickened tread portion 12 and tapering side portions which latter portions terminate in relatively thin flaps 13 adapted to extend over and cover the joints between the beads 8 and the grooves at, and are to be tucked into the space between the demount able rim or base 2 and the main felly of the wheel.

From the foregoing, it will be understood that the improved resilient tire construction described includes, as a part thereof, a demountable rim element, 2 which not only serves to give the necessary support and bow to the inner spring shell 1, but also enables the device as an entirety to be applied to a wheel and removed therefrom in the same manner. as the ordinary pneumatic tires which are carried upon demountable rims. Accordingly, for the purposes of illustration, there is shown in Fig. 1 of the drawings a conventional form of clamping means applicable to wheel fellies and demountable tire rims. These clamping means include the usual upstanding fixed rim 14 carried by the wheel felly and located at one side edge thereof, and cooperating with the usual oppositely located holding clips 15 held in place by the fastening nuts 16 working on the threaded ends of the tie bolts 17 mounted in the wheel felly F. As shown in the illustration, the opposite flap portions 13 of the covering shoe 11 are clampingly engaged by the elements 14 and 15 of the clamping device, so that said elements not only engage and secure the demountable rim in position, but also clamp the said flaps 13. in such a manner, and in such locations, as to provide additional security for holding the edges 6 of the spring shell interlocked Within the grooves 4c of the demountable rim.

Without further description, it is thought that the many features and advantages of the present invention will be readily apparent, and it will also be understood that minor changes in the form, proportion, and details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.

We claim:

1. A wheel tire comprising, in combination with a wheel felly and opposite clamping elements carried thereby, attire body unit including a hollow arched metallic spring shell consisting of a plurality of individual spring plates arranged in overlapping relation, said plates being rigidly connected at the crown of the arch and at their inner ends, and a rigid demountable rim,

having a flat body portion provided with outstanding edge flanges having grooves for receiving the terminal edges of said shell, said unit being held to said felly solely by said clamping elements engaging the rim thereof, and an external shoe having side portions which cover the joint between the spring shell and the demountable rim.

2. A wheel tire comprising, in combination with a wheel felly and opposite clamping elements. carried thereby, a tire body unit including a hollow arched metallic spring shell consisting of a plurality of individual spring plates arranged in overlapping relation, said plates being rigidly connected at the crown of the arch and at their inner ends, and reinforcing cables permanently attached to the terminal ends of said individual arched spring plates to provide opposite heads, and also including a rigid demountable rim having edge flanges provided with grooves for receiving the beaded edges of said spring shell, said unit including the shell and rim being held to said felly solely by said clamping elements, and an external shoe having side portions which cover the joint between the spring shell and the demountable rim.

In testimony whereof we hereunto afiix our signatures in the presence of two witnesses.
